Title: Tube for ring spinning frame and apparatus for connecting a yarn end to said tube
IPC: D01H1/02
Filed: 1962-07-10
Abstract: 990,395. Yarn severing and transfering device. H. GLASTRA. July 10, 1962 [July 13, 1961 (2)], No. 26558/62. Heading D1D. [Also in Division B8] A cop-tube for a spindle of a ring-spinning &c. frame, comprises a flat top 5 with axiallydirected flexible pins 6 which will hold a yarn laid between them at the start of a wind. The pins may be of plastics material and the top 5 may be separated by a stem 4 from a metal reinforcement 3 fitted over the top of the tube to provide a recess engageable by a forked doffing-member. The tube may be used in conjunction with the threadsevering and transferring device shown in Fig. 2. This comprises fixed clamping elements 14, 16, a fixed knife 11 and an elastic block 12 which can be moved towards and away from these members by a rod 18. At the end of a wind, the device lies below an upper doffed packake and above an empty tube 2. The block 12 is moved to the right to trap the yarn in two places, viz, between a rib 15 on block 12 and the element 14, and between the underside of the block and element 16, while the thread is severed by knife 11 co-operating with a recess in the block. As the block continues to move to the right, the rib 15 passes beyond the end of member 14 to release the severed upper part of the thread depending from the doffer package. The device is now moved towards the empty tube 2 so that a slotted member 9 forming the base of the device engages in a recess between the members 3, 5 of the tube, so that it is moved back against the action of springs 19, 24. A member 20 upstanding from the members 9 engages a finger 21 of a V-shaped arm hingedly mounted at 22 so that the arm 23 is tilted to carry the yarn into engagement with the pins 6. At the same time, the block 12 is moved back to release the yarn from clamp 16. The device is then moved back for spinning to begin. The rod 18 may operate a number of devices. Specification 990,396 is referred to.

Title: An improved process for preparing urea formaldehyde lacquer compositions
IPC: C08G12/42
Filed: 1946-09-04
Abstract: Coating compositions are prepared by reacting urea with at least 2.7 mols. of formaldehyde per mol. of urea in an aqueous alkaline solution, distilling off most of the water under reduced pressure, then acidifying the mixture and adding a monohydric aliphatic alcohol having four or more carbon atoms or benzyl alcohol or a lower homologue thereof and a solvent inert to the reactants, but which on distillation will entrain alcohol and water to give a two-phase condensate, the amounts added being no more than will yield a product of the desired concentration, then distilling at atmospheric pressure, with separation of the aqueous and solvent phases of the condensate and recycling of the solvent only, until substantially all water is removed.  Urea may be partly replaced by thiourea, melamine and their derivatives. Formaldehyde may be used as aqueous solution or as substances which will liberate formaldehyde under the reaction conditions, e.g. paraformaldehyde or hexamethylenetetramine.  There are also specified: alkalis-ammonium, sodium and potassium hydroxides and sodium carbonate; alcohols-butyl, amyl, hexyl, octyl, benzyl and mixtures thereof; inert solvents-benzene, toluene, xylene; acids-phthalic anhydride and oxalic, sulphuric and phosphoric acids. There may also be added during the etherification stage minor proportions of methanol, ethanol or n- or iso-propanol or of other resins or resin-forming ingredients, e.g. alkyd resins.

Patent GB-1471947-A (GB)
Title: Film cassette sensing and retaining unit
IPC: G03B21/10
Filed: 1974-06-17
Abstract: 1471947 Film cassettes POLAROID CORP 17 June 1974 [28 June 1973] 26662/74 Heading B8M [Also in Division G2] On inserting a film cassette into a slot in a film-handling apparatus, a retaining latch is actuated, which also energizes a power supply circuit. The cassette is of the type in which a film is exposed in a camera, and then the cassette is transferred to a projector/processor unit. As shown, the cassette 10 is inserted into a slot 14 in the housing 12 mounted in the unit. A latching pin 16 is held in the retracted position (Fig. 4) by a trigger member 30, and as the cassette is pushed completely home, it presses down a finger 42 of trigger member 30, causing it to disengage from pin 16. This can now, under the action of a spring-loaded lever 24, enter an aperture 18 in the cassette, so latching it in position. At the same time, a protrusion 48 on lever 24 closes two normally open switches 52, 54 which energize the circuitry of the film handling apparatus. The cassette has a pair of contacts 76, 78 between which an electrical continuity exists if the film is undeveloped, but does not exist if the film is developed. If the continuity exists, a circuit is established to programme the control system for a cycle which establishes a "development" mode of operation. If the continuity does not exist, at the end of a development cycle a cam 84 on a rotating shaft 88 actuates a cam follower 116 to pivot clockwise as shown. This is linked to a pair of ejector tabs 118, 120 which pivot upwards through slots 148, 146 in the housing 12 to engage and lift the cassette into the Fig. 4 position, whence it may be removed by hand. At the same time another cam 86 on shaft 88 causes a cam follower 90 to pivot clockwise which draws a loop-like link 94 to the right. This engages with a lever 92, which is drawn into engagement with lever 24, which is thus pivoted out of engagement with pin 16, so allowing it to be retracted out of latching engagement with the cassette, enabling the cassette to be withdrawn. A normally closed switch on the outside of the housing has a sensing finger 64 extending into the housing through an opening 66. When the cassette is fully inserted into the housing, it engages the finger 64 to open the switch. If trigger finger 42 has been improperly actuated by an object other than a cassette, switch 60 remains closed, so maintaining a ground return path through a mode change circuit (see Fig. 6, not shown), and causing the control system to cycle back to an "off" status. If it is desired to run the film for projection immediately after development, in order to ensure proper drying, provision is made for disabling the unlatching and ejecting mechanism under these conditions.

Title: A method of and device for automatically winding and guiding cables on impregnating turntables
Inventor: KONCELIK MIRKO
IPC: H01B13/30
Filed: 1963-07-06
Abstract: A turntable, on which a cable is being coiled, carries out a traversing motion in its own plane to permit the cable turns to be correctly positioned side-by-side on the table, the velocity of rotation of the table being continually controlled through stepless gearing to ensure that its linear velocity at the point at which the cable is being fed on to the table is equal to the delivery speed of the cable.  The cable may be supplied to the table via a part-looped-shaped arm to bend the cable to the mean coiling diameter.  The arm may carry a cable delivering roller at its free end and be pivoted at its other end so that when one layer of cable has been laid on the table the arm can swing upwardly to commence the laying of the next layer, the linear movement of the table in the direction of the axis of the delivery roller being then reversed. The arm may be in the form of a tube and a pressing roll 75, Fig. 6 (not shown) may force the cable against two driven rollers 58 so as to bend the cable 1 round to the mean coiling diameter before it is passed into the tube.  This is stated to decrease the friction of the cable in the guide tube and to maintain a more accurate shape of the spirals coiled on the turntable.
